Changelog

All clj-otel-* module versions are released in lockstep to Clojars.

x.y.z versions listed below do not follow semantic versioning. Instead, development proceeds on a linear path where z increases for batches of incremental changes and y increases (with z reset to 0) when milestones are reached.

Breaking changes will be documented here.

Until version 1.0.0 there is a greater possibility of breaking changes, highlighted with [BREAK] below.

`0.x` changes

`0.2.0` (in progress)

Add support for Metrics API
Add implementations of the following HTTP server metrics for use by applications not run with the OpenTelemetry instrumentation agent:
- http.server.active_requests
- http.server.duration
- http.server.request.size
[BREAK] The parameters for function add-route-data! have changed, there is a new parameter to specify the HTTP request method.
[BREAK] The pattern for using clj-otel middleware and interceptors in applications has been revised. The revised pattern adds new middleware wrap-route, wrap-active-requests and wrap-metrics-by-route and interceptors route-interceptor, active-requests-interceptor and metrics-by-route-interceptors to capture matched routes in HTTP server spans and HTTP server metrics. The pattern also ensures all requests are recorded, including those which do not match any route.
New module clj-otel-instrumentation-runtime-metrics to provide access to JVM runtime metrics instrumentation for applications not using the OpenTelemetry instrumentation agent.
Added aliases in examples
- :metrics-* to control export of metrics
- :logging-* to control application logging
Bump deps:
- OpenTelemetry 1.25.0
  - [BREAK] When using autoconfiguration for a manually instrumented application, include the new JVM option "-Dotel.java.global-autoconfigure.enabled=true" or environment variable setting OTEL_JAVA_GLOBAL_AUTOCONFIGURE_ENABLED=true
  - Methods to statically set the server host name attribute on server spans have been removed, as static data is better represented as an OpenTelemetry resource.
    
    [BREAK] The function add-server-name! has been removed.
    
    [BREAK] The option :server-name has been removed from the middleware and interceptors for server span support.
  - [BREAK] Module clj-otel-extension-aws renamed to clj-otel-contrib-aws-xray-propagator
  - [BREAK] Module clj-otel-sdk-extension-aws renamed to clj-otel-contrib-aws-resources
  - [BREAK] Module clj-otel-sdk-extension-resources renamed to clj-otel-instrumentation-resources
